Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the board-to-board connector 1 of the present invention includes two male-female connectors 10 with the same structure.

Please refer to FIG. 3 in conjunction with FIG. 2 . Each hermaphrodite connector 10 includes an insulating base 11 , female terminals 12 , male terminals 13 and a plurality of solder fluxes 14 . The insulating base 11 has a female body 111 and a male body 112 . The main part 111 is roughly in the shape of a cuboid, and has a bottom plate 1111. The opposite sides of the bottom plate 1111 protrude vertically upwards along the longitudinal direction of the bottom plate 1111 to a pair of first side walls 1112. The other opposite sides of the bottom plate 1111 are vertical along the transverse direction of the bottom plate 1111. A pair of second side walls 1113 protrude upwards, and the first side wall 1112 , the second side wall 1113 and the bottom plate 1111 enclose a receiving chamber 1114 . The mother part 111 is provided with a plurality of female terminal grooves 1115 arranged longitudinally at equal intervals at intervals. The female terminal grooves 1115 extend from the first side wall 1112 on one side to the first side wall 1112 on the other side along the bottom plate 1112. Each female terminal groove The terminal groove 1115 accommodates corresponding female terminals 12 , and one end portion of each female terminal 12 passes through the female terminal groove 1115 and extends into the receiving cavity 1114 . A middle part of the upper surface of the second side wall 1113 defines a solder flux groove 15 penetrating up and down, and the flux flux groove 15 is used for receiving the solder flux sheet 14 .

The male body part 112 is also substantially rectangular parallelepiped, and its length is greater than that of the female body part 111 . The male body part 112 has a base plate 1121, which is formed by extending outward from one side of the bottom plate 1111 of the female body part 111. The third side wall 1122 is also provided with a fluxing groove 15 penetrating up and down in the middle of the upper surface of the third sidewall 1122 , and the fluxing groove 15 is also used to accommodate the fluxing sheet 14 . A nesting portion 1123 protrudes from the middle of the base plate 1121. The nesting portion 1123 is located between the two third side walls 1122 and away from the first side wall 1112. The length and width of the nesting portion 1123 are slightly smaller than the receiving cavity. 1114 length and width. There is a distance between the nesting portion 1123 and the adjacent first side wall 1112 , which is slightly larger than the thickness of the adjacent first side wall 1112 . The nesting portion 1123 is also spaced from the third side wall 1122 by a distance slightly greater than the thickness of the second side wall 1113, so that the nesting portion 1123 and its adjacent first side wall 1112 and third side wall Between 1122 is formed a receiving groove 1124 roughly in the shape of "ㄩ". A side of the nesting portion 1123 close to the first sidewall 1112 defines a plurality of male terminal grooves 1125 arranged longitudinally at equal intervals, each male terminal groove 1125 penetrates the substrate 1121 and accommodates a corresponding male terminal 13 .
